Hang Tough: Total-Body TRX Workout

About This Workout

There is a simple tool in your gym that can turn up the toning of just about any body-weight move you do. And if you haven't gotten the grip of a TRX suspension trainer yet, here's your hookup. "You'll recruit more muscle fibers with each rep because you're working on an unstable surface," says Marianna Biribin, a trainer for Exceed Physical Culture studio in New York City, who designed — and demos — the total-body routine on the next page using the tricked-out straps. (No gym? Try the at-home version of TRX, $200, trxtraining.com.) Do two sets, and bump it up an extra 10 reps or a set once you've learned the ropes.

Limbo

Targets back, arms, and abs

Stand with feet hip-width apart, facing TRX, holding one handle in right hand (stand close enough to anchor to keep a loose tension in strap.)

With feet flat, lean torso back, bending knees so body forms a tabletop position and strap is completely taut with right arm extended; reach left hand toward floor directly behind you as low as you can, looking behind you as you lean back.

Using right arm, pull body up to start position, keeping right arm close to ribs; reach left hand toward anchor to briefly grip strap.
